FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent N 0. 394,171, dated December 11, 1888. Application filed July 16, 1888. Serial No. 280,106. (No model.)

To (all wk 07m it um/y cancer/1 Be it known that I, (Home F. GRANT, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in l m1ntain-Pens; and I do hereby declare the following to be a full, clear and exact description thereot', reference being had to the accompanying drawings, forming part of this specification, in which- Figure I is a plan view of my improved ruling-pom. li igure 2 isalongitudinal sectional view on tiheline .1 1 of Fig. Fig. 3 is a plan view of the worm-sleeve piston an d nozzle, the outer casing being indicated by dotted lines. Fig. 4.- is a detached view of the piston. Fig. 5 is a like view of the slotted guide-sleeve. Fig. (3 is an enlarged cross-section 011 the line 1 1 of l igs. 1 and 2. Fig. 7 is a longitudinal sectional view of a modified form of penpoint. Fig. 8 is a cross-section on the line z of Fig. 7.

Like letters and figures indicate like parts in each.

In the drawings, 2 I) represent the outer casing made in two parts, the forward portion, 2, serving as an ink-fountain, while the rear portion, E3, serves as a casing to the feed mechanism. This teed .n1echanis1n consists of a piston-head, l, situate within the fountain casing 2, the piston rod extending through the packing-rings 5 ti, which are secured in the meeting ends of the casings 2 3 into the casing 3. \l'ithin the casing 33 the piston-rod is provided with one or more projecting pins, 7, which pass through a longitudinal slot, 8, in the guide-tube I and engage with the worm-slot .10 of the tube 11. The inner guide-tube, 0, is secured at its end in the packing-ring 5 of the casing 2, as is shown in. Figs. 2 and 5. The other end of the tube 9 within the casing 3 is upset or ei'llarged out:- side of the outer worm-tube, 1. The wor1ntube 11 tits within the packing-ring 6 and is secured thereto. The packing-rings 5 and (i are secured in the casings 2 and 3 by suitable screw-threads. At the forward end of the casing 2 is a tapered mouth-piece or nozzle,

13, secured in the case 2 by a suitable screwthread. 011 the outer portion of the mouthpiece 13 is a screw-thread, by which a right line or ruling-pen, it, is secured. This pen It has spring or hinge jaws tending to close on each other at the point. By screwing the pen down on the tapered lllOlllll-PltCO thejaws are caused to separate, and thereby the width or heaviness ot' the line to be produced may be regulated. Instead of the spring-jaws described, the jaws may be held together by a screw-bolt and nut, as shown in Figs. 7 and 8. Owing to the central 1nouth-piece or nozzle, the bolt 1!; is provided with an eye, 17, between the jaws, and the jaws are coi'ltracted or loosened by turning the nut 18.

The operation is as follows: By turning the casi 11g 3, the guide-rod 9 being held by the ring 5 in the case 2, the worm ll turns with the case 3 and, acting on the pins '7, causes the piston-head ii: to advance so as to feed the ink to the pen, or to reccde and draw the ink into the :t'ountain reservoir when it is necessary to till the same.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The ink-tou11tain 2 and the mouth-piece 13, titted thereto at one end, and the packingring 5, titted to the other end of said fountain and provided with the guide-tube 9, combined with the piston t, arranged in the ink-fountain and. having its stem extended into the guidetube, and a worm engaged with said stem and adapted to be rotated to adjustthe piston, substantially as described.

2. The ink-fountain, the mouth-piece 13 thereof, and the ruling-pen 1%, adj ustably secured to said n1outh-pi eee, combined with the packing-ring 5, its slotted tube 9, the worm 1 t,thep1'ston c, having its st'eni extended into the tube 9 and engaged by the worm, and the external easin g, substantially as described.

In testimony whereof I have hereunto set my hand this 20th day of June, A. I). 1.888.

OSCAR F. GRANT.
